Biobased polyamides - the sustainable alternative
Biobased polyamides, such as Polyamide 11 (short: PA11), have been used for several decades in various markets due to their durability and outstanding technical properties. Biobased polyamides are derived from castor oil among others, which comes from the seeds of the castor plant (Ricinus communis).
This makes them a sustainable material with a low carbon footprint (see diagram). Biobased polyamides can be easily recycled, helping to further reduce a company’s ecological footprint.
Advantages
Additionally to their natural origin, biobased polyamides are considered high-performance plastics, mainly due to their numerous advantageous properties compared to other materials:
High chemical resistance
Biobased polyamides are resistant to a variety of chemicals (including oils, fats, and various solvents).
Low density
Biobased polyamides are approximately 20% lighter than polycarbonate. This makes them a valuable raw material for applications where weight plays an important role.
High scratch and impact resistance
Both at room temperature and as well as at very low temperatures, biobased polyamides impress with their high impact resistance and high scratch resistance compared to other polymers.
Low moisture absorption
Due to their low moisture absorption, biobased polyamides can be used in a variety of wet environments. Additionally, alcohol, acids, and esters are only minimally absorbed by biobased polyamides.
